Title: Improvements in or relating to shaped resilient articles
IPC: B05D7/26
Filed: 1942-09-28
Abstract: 574,605. Agglutinated fibrous materials. WOODMAN, T. C. Sept. 28, 1942, No. 17190/44. Divided out of 574,575. [Class 140] [Also in Groups IX and XXV] A resilient article for use in place of rubber is made by dipping a shaped body of matted fibres in a dope containing cellulose acetate, removing the body while the penetration of the dope is still incomplete so as to leave a core in which the spaces between the fibres are not filled up, and drying. The cellulose acetate may form an impervious skin on the surface of the article. The impregnation may be effected in a chamber in which the body or bodies are subjected to vacuum before the dope is run in. and later subjected to pressure to force the dope in. The dried impregnated body may be re-dipped once or oftener. The shaped body may comprise animal fibres, e.g., wool, artificial filaments or fibres, or both. Shaped blocks of wool felt are subjected to vacuum, are covered with a solution of cellulose acetate and triacetin, diethyl- or dimethyl-phthalate in a mixture of acetone, benzene, ethyl alcohol, and diacetone alcohol. which may contain powdered graphite, and the vacuum is then released. The blocks are removed, drained, dried, and converted into the cloth-engaging parts of loom temples by boring to take a spindle and turning down ¢ inch diameter. Dyes, pigments, abrasive materials, solid lubricants, e.g., graphite or talc, and fireretardants may be added to the dope or incorporated in the fibrous body before impregnating. The products are suitable for shock-, pressure-, or vibration-absorbing stops, buffers, or mountings,. e.g., door stops, buffer pads for water closet seats, buffers in textile looms to check the motion of the picking sticks or as the shock-absorbing pads mounted on frogs at either side of the loom.

Title: Improvements in the manufacture of anthraquinone
Filed: 1921-07-01
Abstract: In the oxidation of anthracene to anthraquinone using nitrogen oxides as catalyst, (1) an acid solvent or suspending-agent, not necessarily anhydrous, is employed, and (2) a nitric-acid fixing agent, e.g. sodium acetate, must be present.  When the nitrogen oxides are introduced as a nitrite, the interaction of the acid solvent therewith produces the fixing agent; whereas when the nitrogen oxides are added in the form of fuming nitric acid or in the state of liquid or gas, the fixing agent must be introduced before the reaction commences.  According to the examples, anthraquinone is produced by passing oxygen through a mixture of anthracene and glacial acetic acid which contains some sodium nitrite or to which fuming nitric acid and sodium acetate have been added.

Title: Treatment of molten metals and alloys
Filed: 1936-07-08
Abstract: In the treatment of molten metals and alloys for the purpose of removing occluded gases &c. the melt is subjected to the action of . ultra sound waves which vary in frequency or intensity or both at intervals which are short in comparison with the duration of the process and which may be several or many times as long as the period occupied by a single sound vibration.  The intensity or the frequency of the vibrations or both may pulsate between values, one of which is at least 10 times that of the other, the time of the high frequency and/or intensity being considerably shorter than that of the low frequency or intensity.  The variations in frequency &c. may be caused to occur in repeated cycles so as to produce the effect of beats or intermittent actions by the co-operation of two generators of closely neighbouring frequencies, the two wave systems produced forming a wave the nodal points of which move about in the melt.  The melt may be subjected to the action of vibrations of two or more frequencies, the relative ratios of which are not less than 3 to 1 and one or more of the frequencies may be produced intermittently while the others are produced continuously.  The action of the vibrations may be varied during the process and the intensity increased, but not to such a point that cavitation occurs.  After the main treatment and to remove the last trace of gas from the melt, cavitation may be induced.  The variations may be produced by variations in the generator or when using a continuously and uniformly acting generator by varying the manner in which the transmitter transmits vibrations to the melt.  In the same generator the fundamental harmonic and one or more of the higher harmonics may be produced alternatingly or concurrently, and a generator may be caused to act alternately on two or more transmitters, which transmit vibrations in succession to the same or different melts.  The treatment of technically pure aluminium is described in detail. p
